Stalker&Yandere

Yandere-chan is just an ordinary girl with ordinary hobbies, ordinary friends, ordinary problems, and one not-so-ordinary crush. She has feelings for the man standing in her street --not a stalker-- who's just loitering about --definitely not a stalker-- and who occasionally tries to look through her window --most definitely not a stalker--. But Yandere-chan doesn't know who this mysterious man is, why he's standing there and if he might be interested in her as well. Should she approach him and confess her feelings to him? Or should she keep her feelings hidden to avoid a heart-break?
